# 时间戳与 ISO8601

### **ISO8601**

[ISO8601](https://en.wikipedia.org/wiki/ISO_8601) 是一个用于格式化日期和时间的国际标准，常被数据库使用。

使用 "as iso8601" 转换为此格式：

```
April 1, 2019 3:30pm as iso8601 | 2019-04-01T15:30:00+11:00
```

使用 "to date" 转换为常规日期格式：

```
2019-04-01T15:30:00 to date | 1 April 2019 at 3:30 pm
```

### **时间戳**

[Unix time](https://en.wikipedia.org/wiki/Unix_time) 是一种描述时间点的系统，常用于编程。时间戳是从“参考日期”（1970年1月1日）开始经过的秒数。

```
April 1, 2019 to timestamp | 1554109200
1559740303.48 to date      | 5 June 2019 at 11:11 pm
```

要获取当前时刻的时间戳，请使用 **current timestamp**

```
current timestamp | 1559740303.48
```

#### **毫秒时间戳**

您也可以将毫秒时间戳转换为日期

```
1733823083000 to date | 10 December 2024 at 8:31:23 pm
```
